Schmitt Trigger - CD40106B

The CD40106BE consists of six Schmitt-trigger circuits. Each circuit functions as an inverter with Schmitt-trigger action on the input. The trigger switches at different points for positive- and negative-going signals. The difference between the positive-going voltage (VP) and the negative-going voltage (VN) is defined as hysteresis voltage (VH).

  • Schmitt trigger action with no external components
  • Hysteresis voltage typ. at 0.9V at VDD = 5V, 2.3V at VDD = 10V, and 3.5V at VDD = 15V
  • Noise immunity greater than 50%
  • No limit on input rise and fall times
  • Standardised, symmetrical output characteristics
  • 100% tested for quiescent current at 20sV
  • Maximum input current of 1µA at 18 V over full package temperature range; 100nA at 18V and 25°C
  • Low VDD to VSS current during slow input ramp

Schmitt Trigger - CD40106B Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
